Question

我试图通过其API将文档上传到DrChrono。当我转到指定的url并使用设备安全性（authenticate_user！）时，从Web浏览器，它下载68毫秒。但是，当我运行以下代码时，我收到超时错误。 PDF文件是一页，使用Prawn制作。

  open('http://' + host + '/recording/' + recording.id.to_s + '/analysis.pdf') do |file|
    params = {
      'document' => file.read,
      'doctor' => 'https://drchrono.com/api/doctors/' + doctor.id,
      'patient' => 'https://drchrono.com/api/patients/' + recording.patient.chrono_id.to_s,
      'description' => 'Report',
      'date' => Time.now.strftime("%Y/%m/%d").gsub('/', '-')
    }
    response = HTTParty.post('https://drchrono.com/api/documents', :headers => headers, :body => params)
    data = JSON.parse(response.body)
  end

我的日志显示在超时后

Started GET "/recording/131/analysis.pdf" for ip at 2014-05-29 10:18:43 -0700
Processing by Dashboard::RecordingsController#report as PDF
  Parameters: {"id"=>"131"}
Completed 401 Unauthorized in 8ms

我最初认为这是因为我的设计安全性没有通过正确的参数。因此，我将此特定控制器切换到使用令牌认证系统的API安全性。唯一真正的变化是现在打开后的网址包含一个身份验证令牌。

但是，我仍然在完全相同的位置得到超时错误，但现在它后跟

这让我相信初始超时与缺乏授权无关，而是因为即使访问未被拒绝，我仍然会超时。

我研究了我的设置，而这（Open an IO stream from a local file or url）表明我正走在正确的道路上。

由于pdf文件实际上是一个页面，通常只需要68秒，我不明白为什么我会遇到任何超时问题。有什么想法吗？

编辑：

此人似乎遇到了类似的问题（Rails open-uri breaking on path），但建议的解决方案我已经做过了（瘦而不是默认服务器）。

编辑：

让我们更具体一点。这很有效。

  content = open('http://www.google.com').read

这些没有。

  content = open('http://localhost:3000').read
  content = open('http://' + host).read

我有一个为我的Faye运行的puma服务器和一个通过rails运行的瘦服务器。

Rails：open-uri，pdf到api post，timeout
